[Multiple penetrating brain injuries caused by a nail gun: a case report]. / Heridas múltiples penetrantes intracraneales causadas por pistola de clavos: caso clínico.

Multiple and self-inflicted penetrating brain injuries (PBI) rare. PBI are rare. We report the case of multiple self-inflicted PBI in a 45 year old man caused by a nail gun. He was admitted to after shooting four nails into his head and one into his thorax. We review the literature on the topic and describe how this case was successfully managed in our hospital.

[Primary CNS Lymphoma: bibliographical review and experience at the Hospital of Navarre in the last 5 years (2000-2004)]. / Linfoma cerebral primario: revisión bibliográfica y experiencia en el Hospital de Navarra en los últimos 5 años (2000-2004).

Primary cerebral lymphoma (Primary CNS Lymphoma, PCNSL) is an aggressive non-Hodgkin lymphoma that originates in the central nervous system without evidence of lymphoma in any other localization at the time of diagnosis. Primary cerebral lymphomas are less well-known and are characterized than their homologues the systemic lymphomas, as they are an entity whose frequency was scarce until a few decades ago. However, the great rise in incidence that this pathology has undergone over the last three decades, and which is still unexplained, makes more studies necessary to better understand the etiopathology of this entity. Thanks to the new systems of treatment, the prognosis of this pathology has improved significantly in recent years. Nonetheless, treatment of primary cerebral lymphoma continues to give rise to numerous controversies at present due to its high neurotoxicity in patients over 60 years of age, a group of patients frequently affected by this pathology. To resolve these and other questions it is necessary to deep in the study of primary cerebral lymphoma and to carry out high quality clinical trials.

Solitary thoracic intradural extramedullary plasmacytoma.

The bodies of the vertebrae are common locations for plasma cell diseases such as multiple myeloma and solitary plasmacytoma. Secondary invasion of the epidural space is infrequent but can cause neurological symptoms. Spinal cord compression due to pure intradural plasma cell infiltration is very rare. The authors report a 25-year-old woman who developed a progressive difficulty in walking due to a solitary spinal dural plasmacytoma. This is the first reported example in the English language literature of a purely intradural spinal plasmacytoma in a patient without other myelomatous lesions. An entirely intradural solitary plasmacytoma has a relatively better prognosis.

[Intracranial hemorrhage from an arteriovenous malformation (AVM) in a tuberous sclerosis patient]. / Hemorragia intraparenquimatosa por una malformación arteriovenosa en una paciente con esclerosis tuberosa.

We describe a previously diagnosed tuberous sclerosis patient that arrived to the hospital with an intracerebral hemorrhage whose origin was an arteriovenous malformation (AVM). A craniectomy was performed and the hematoma was evacuated with the alleviation of the patient. Although the association between tuberous sclerosis and intracerebral hemorrhage is known in the literature it has never been described associated with an AVM.
